Air Bag Filters

This course will enable participants to acquire knowledge and develop skills on how to implement a systematic and effective preventive maintenance and performance monitoring procedure for air bag filters also it will enable participants to be ready as a competent person to operate air bag filters after complying with other requirements. also it will be good for the industry by minimizing the occurrence of breakdown of cyclones that may result in non compliance with emission standards.

• Introduced to the principal similarities of and differences between bag filters and other filters
• Able to identify the two major applications and two major limitations of both bag filtration and other filtration.
• Able to identify the main components of bag filtration systems.
• Able to identify the characteristics of source water that can impact the effective operation of a bag filter system.
• Aware of the reasons why site specific piloting should be considered prior to installing a bag filter system.
• Receive an explanation of the advantages and disadvantages of air bag and filtration systems.
